javascript - 如何合并这两个 forEach 循环(只使用一个)？

Question

以下代码采用两个数组(fields 和 photos)，获取它们字段的名称和值，并将它们添加到一个新数组(panoramas ):

功能:

const panoramas = this.uploads.finished.map(photos => {
   let panorama = {}
   fields.forEach(field => { panorama[field.name] = field.value })
   photos.forEach(photo => { panorama[photo.name] = photo.value })
   return panorama
})

输入:

字段:

[{
  name: "name"
  type: "hidden"
  value: ""
}, {
  name: "description"
  type: "hidden"
  value: ""
}, {
  name: "photo"
  type: "file"
  value: ""
}, {
  name: "photo2"
  type: "file"
  value: ""
}]

照片:

[{
  name: "photo"
  value: "1.png"
}, {
  name: "photo2"
  value: "2.jpg"
}]

输出:

全景图:

[{
  name: "name"
  type: "hidden"
  value: ""
}, {
  name: "description"
  type: "hidden"
  value: ""
}, {
  name: "photo"
  type: "file"
  value: "1.png"
}, {
  name: "photo2"
  type: "file"
  value: "2.png"
}]

如您所见，我在 map 中使用了两个 forEach 循环。有没有办法只使用一个 forEach？

Answer 1

fields.concat(photos).forEach(obj => { panorama[obj.name] = obj.value });
